Expression of TLR4 and NF-κB p65 in the placenta of different pregnant groups.

<p>Immunohistochemistry for TLR4 (A-B) and NF-κB p65 (C-D) in paraffin-embedded placental tissue sections (4 μm) from the saline-treated and LPS-treated pregnant rats. Corresponding concentrations of anti-IgG served as non-specific controls (E-F). Data are expressed as mean ± SEM, N = 1–2 placentas for 10 rats/group, *<i>P</i> < 0.05 vs. saline-treated pregnant group. Magnification 400 ×. Bar 100 μm.
